When a watcher-triggered reconciliation is already running after startup, this passes None for the fallback receiver, and the receiver itself was moved exclusively into the now-completed startup task. shutdown_without_waiting_for_test therefore cannot cancel that reconciliation; it merely detaches the server task, allowing the job to continue starting or reloading runtimes after fixture cleanup. Propagate a cloneable fallback signal to every admitted reconciliation rather than limiting it to startup.

When operation_result fails because the startup reconciliation is wedged, this unconditional graceful cleanup waits for that same startup task: RunningDaemon::shutdown() reaches stop_startup_task, which awaits the task without a bound. Consequently the new request/scenario timeout still cannot return its diagnostic and the test remains stuck until nextest kills it. On the timeout/error path, invoke the non-waiting fallback before cleaning runtimes, or bound graceful shutdown and fall back.

When fallback arrives during a matching-runtime reload whose admin /load request is stalled, this check has already passed and the following load_runtime_config(...).await does not observe cancellation. The detached reconciliation can therefore outlive fixture cleanup with promoted configuration and replacement-required metadata until its independent request timeout, after which restoration may block again. Race the reload with the fallback signal and run the rollback/restoration path immediately on cancellation.

Fallback cancellation needs a commit boundary before this is mergeable.
Reviewed changes across the daemon fallback lifecycle, fixture containment, and CI timeout policy.
- Fallback shutdown — adds a test-only nonblocking daemon shutdown signal and cancellation-aware gateway/worker reconciliation.
- Runtime recovery — stops fresh runtime starts and restores matching reloads when cancellation interrupts an in-flight transaction.
- Fixture bounds — adds bounded request/scenario helpers, independent
Dropcleanup, and deadlock/cancellation regressions. - CI containment — configures nextest termination, a finite Rust job timeout, and cancellation of superseded runs.

When fallback shutdown fires while a non-Gateway resource reconciliation is blocked, this branch wraps the result without ever passing or racing the fallback receiver; system and project jobs likewise await resource installation/project application before first observing it. Because shutdown_without_waiting_for_test detaches the server task, these operations can continue mutating state after fixture cleanup and can still hold runtime teardown indefinitely. Fresh evidence beyond the earlier receiver-routing finding is that the receiver now reaches watcher and foreground jobs but is explicitly ignored by this non-Gateway dispatch. Propagate cancellation through every long-running reconciliation phase.

✅ No new issues found.
Reviewed changes since the prior Pullfrog review, focusing on the rewritten fallback-cancellation boundary and expanded fixture containment.
- Made cancellation commit-safe — preserved pending matching reloads without a competing restore load, while fresh starts are stopped and cleaned before cancellation propagates.
- Extended fallback propagation — carried a cloneable shutdown signal through startup, foreground socket, watcher, queued background, and health-recovery reconciliation paths, with cancelled jobs abandoned cleanly.
- Hardened fixture ownership checks — added process-group cleanup regressions and serialized worker port handoff through runtime ownership publication.
- Improved macOS fixture reliability — replaced copied signed fixture executables with generated scripts and expanded bounded request/scenario diagnostics.

Fallback shutdown can still replace an actionable reconciliation error with generic abandonment.
Reviewed changes since the prior Pullfrog review at f03113b, focusing on the expanded reconciliation cancellation boundaries.
- Extended fallback cancellation — added shutdown checkpoints across system, Managed Resource, and Project discovery, resource, apply, cleanup, and gateway phases.
- Preserved completed-phase errors — retained resource, project, and cleanup failures when cancellation is observed between phases.
- Released blocked fixture requests — added a test-only release hook so nonblocking daemon teardown can unblock an injected synchronous resource client.
- Expanded lifecycle coverage — added regressions for an in-flight system resource phase and blocked fixture request cleanup.

When shutdown_without_waiting_for_test is invoked while a foreground update system job is blocked in a manifest request, download, or install, this newly supplied receiver is never forwarded through the update branch. Dropping the server task therefore detaches the update, which can continue installing artifacts and subsequently reconcile or start runtimes after fixture cleanup; thread the fallback signal through update execution and its reconciliation/compensation phases.

When fallback shutdown arrives while the external Caddy or FrankenPHP validator is stalled, cancellation is checked only after promote_runtime_config_tree(...).await returns, so the detached reconciliation and validator process remain alive until the independent 10-second validation timeout. This can outlive fixture cleanup; race validation against the fallback signal and terminate the validation process group on cancellation rather than merely checking afterward.

Under the normal concurrent nextest scheduler used by .github/workflows/ci.yml, this test and fallback_shutdown_cancels_watcher_reload_and_preserves_pending_worker both scan the identical 55_000..59_999 range through the raw helper and drop their reservations before their runtimes bind. If the second process reserves after the first drop but before its bind, both fixtures select the same port and one fails spuriously; use FoundationWorkerPortHandoff through publication or assign disjoint ranges.

When a fixture supplies a blocking ResourceHttpClient and issues ManagedResourceUpdateCheck, the fallback receiver is forwarded only to RunJob; the separate update-check branch awaits spawn_blocking(update_check) without observing it. Because fallback teardown now preserves and joins connections, shutdown_without_waiting_for_test can leave this blocking task alive through fixture cleanup and Tokio runtime teardown can still hang. Propagate an unblock/cancellation mechanism through the update-check path as well.

process-group cleanup cannot signal a reused PID after the validation leader has

ManagedResourceUpdateCheck so an injected ResourceHttpClient cannot keep

Make ManagedResourceUpdateCheck safe for injected clients during fallback shutdown. The default UreqResourceHttpClient has finite manifest timeouts. However, the public startup API accepts any ResourceHttpClient, and the trait does not require a timeout or cancellation mechanism. If an injected get_text call blocks, spawn_blocking remains active while fallback shutdown joins the connection task. Require bounded injected clients, or make this branch stop awaiting the blocking operation when fallback shutdown begins.

In `@crates/daemon/src/server.rs` around lines 296 - 298, Update the fallback
shutdown handling around ManagedResourceUpdateCheck so an injected
ResourceHttpClient cannot keep shutdown blocked when get_text hangs
indefinitely. Either enforce a bounded timeout contract for all injected clients
or stop awaiting the spawn_blocking operation once fallback shutdown starts,
while preserving normal manifest-check behavior.

Reviewed changes since the prior Pullfrog review at 66aa052, focusing on the completed fallback-shutdown containment and error-preservation paths.
- Preserved reconciliation failures — retained accumulated system and Project errors when gateway cancellation wins the race, resolving the prior generic-abandonment regression.
- Contained config validation — made Caddy and FrankenPHP validation cancellation-aware, bounded validator process-group and output cleanup, and guarded candidate root and fragment removal.
- Extended job cancellation — carried fallback handling through queued and active foreground updates, Managed Resource preparation and readiness, and idle daemon connections without changing graceful production shutdown.
- Expanded lifecycle regressions — covered validation descendants, candidate cleanup, update mutation boundaries, resource readiness, foreground updates, and idle-client draining.

The latest delta safely retains macOS process-group ownership with an unreaped anchor before signaling and moves residual validator reaping off the Tokio worker. Focused validation, formatting, and daemon Clippy checks pass; macOS 14 and macOS 26 CI lanes also pass.

Closes #352.
Closes #354.
This is the containment layer for test-fixture lifecycle failures: daemon fallback cleanup is nonblocking, fixture requests and scenarios are bounded, CI terminates wedged tests and jobs, and shared worker-port handoff is coordinated across fixture processes. The ownership-safe process-lifecycle work for #349 follows in the next stacked PR.
